=== Notes (Shaul) === \\

  * Ragnhild thinks that C2 estimation of CMB spectra is ok. Proceeding forward. 
  * {{ ::nilc_pico_20210701.pdf | MR shows an update with results for model 96}}. Kris suggests to integrate the likelihoods to get proper limits. 
    * Kris: you are doing r=0.003 and r = 0; but what if you have small r, but non-zero? Why are we using r =0.003? 
    * Some discussion about the level of delensing. Why are we using 60%? **SH to contact Julien Caron**. 
    * Kris: What are you assuming about the spectral index for synchrotron? We should not assume a uniform spectral index. What beta per pixel? **notes are not clear about the answer**
  * Kris discusses his small scale synchrotron model: model is phenomenological, not physically motivated. It is tweaked to insert small scale 'mathematically', but not to violate what's know about the sky. 
    * He takes Planck 353 GHz dust and modifies it. So the small scale synchrotron would be highly correlated with Planck's dust in small patches of the sky.
